NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 794,929, dated July 18, 1905. Application filed July 6, 1904:. Serial No. 215,495.

To all whom, it may concern.-

Beitknown that I, RALPH DUNNE, pictureframer, of Dunedin, New Zealand, have invented a certain new and useful Non-Refillable Bottle, of which the following is a specification.

The invention consists of the features and combination and arrangement of parts hereinafter described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the drawings, Figure 1 is a section of a bottle with stopper in position. Fig. 2 is a Fig. 3 is a section of the stopper.

There is a stopper 1 made of a substantially impenetratable substance, preferably glass, and having a channel 2 cut in one side to permit of the passage of air .therethrough when the stopper is placed in position in the neck 3 of the bottle 4:. The stopper is chambered, a small part 5 of the upper portion of the chamber being oblong in cross-section and a larger lower part 6 of the chamber being frustum-shaped in cross-section, the latter being to allow of a limited movement of the valve hereinafter described within a certain range and the former being to restrict as much as possible the outlet from the stopper for greater security against tampering. The upper part 5 of the chamber is provided at one side near the top with an opening 7, entering into another opening 8. formed between the inner surface of the neck 3 of the bottle and the side of the stopper, aportion of the stopper at its upper end being cut away for the purpose, as shown at 8 in Fig. 2. IVithin the lower part 6 of the chamber there is a valve 9 under tension of a spring 10, consisting of a straight piece of rubber or a spiral of some suitable material. As shown, one end of the spring is attached to the valve 9 and the other end to the under surface 11 of the upper portion of the stopper. When a spiral spring is used, a guiding and supporting rod 12 is provided therefor, secured to or cast integral with the upper portion of the stopper for the purpose of giving steadiness to the spiral spring. On this rod at its lower end there is a ring-piece 13 for the purpose of preventing the valve from falling ofl the rod when the stopper is being inserted in the neck of the bottle.

Into a channel formed round the lower portion of the stopper a cork or the like ring 14: is inserted for the purpose of insuring a close fit of the stopper in the bottle.

Within the neck 3 of the bottle 4:, preferably at the bottom of the neck, there is an annular flange 15. integral with the neck 3, which forms a support for the stopper 1 an also a seating for the valve 4 of the stopper 1.

When the bottle is filled, the stopper 1 is thrust into the neck until it rests on and is supported by the flange 15, and an ordinary cork 16 is inserted in the neck above the stopper.

The stopper cannot be withdrawn by any instrument inserted down the neck on account of the hardness of the material of which the stopper is composed. The construction of the openings and chamber and their relative positions in the stopper and the position of the valve prevents the insertion of a wire to destroy or remove the valve. This arrangement permits of the contents of the bottle being poured out, but prevents any fluid from being passed into the bottle.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination, with a bottle having an inwardly-extending flange in the neck thereof, a stopper having a chambered lower portion and a lateral passage at its upper end communicating at the side with the mouth of the bottle, an annular valve-seat at the lower end of said stopper, a valve cooperating therewith, and a spring bearing on said valve, substantially as described.

2. In combination, with a bottle having an inwardly-extending flange in the neck thereof, a stopper having a chambered lower portion and a lateral passage at its upper end, communicating at the side with the mouth of the bottle, and having an air-passage at the side opposite said lateral passage, an annular valveseat at the lower end of said stopper, a valve cooperating therewith, and a spring bearing on said valve, substantially as described.

3. In combination, with a bottle having an internal annular flange in the neck thereof, a stopper having an air-channel down one side, and having an interior chamber oblong in cross-section at the upper part and communicating at theside opposite the air-passage with the space above the stopper, and of frusto-conical shape at the lower part, an inwardly-extending annular valve-seat at the lower end of said chamber, a valve resting thereon, and a spring bearing on said valve, substantially as described.

4. In combination, with a bottle having an internal annular flange in the neck thereof, a stopper having an air-channel down one side, and having an interior chamber oblong in cross-section at the upper part, and communicating at the side opposite the air-passage with the space above the stopper, and of frusto-conical shape at the lower part, an inwardly-extending annular valve-seat at the lower end of said chamber, a valve, resting thereon, and a spring bearing on said valve, and a rod in the chamber for guiding the valve, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
